I have 2 environments that I (hope) think are identical. They are both setup with:

MW 1.25alpha PHP 5.3.17 Collection 1.7.0 (1618025)

In the Dev environment, Collection works perfectly. In the Prod environment, I'm seeing this error:

<Greenlet at 0xd43eb0: <bound method start_fetcher.run of <mwlib.apps.make_nuwiki.start_fetcher object at 0xdbba50>>> failed with  RuntimeError

So it's failing on the start_fetcher.run method, but I can't seem to figure out why. Is this likely some system configuration thing?

Solved.

This was a DNS issue. We had to add and entry to /etc/hosts so that the server could talk to itself, basically.

Hi, I am getting the same error. Do you happen to know what you put in your /etc/hosts file to resolve this?

I am getting same error after enabling SSL. Could you share how did you resolve this issue

Solved, again the old issue with "localhost" and "192.168". I supposed that the issue was removed, but I was wrong.

There is a check for the incoming addres in file nserve.py at around line 286 which returns False if the calling server (media wiki collection address) starts with 192.168 or is localhost.

Comment the statement or set its return to True. Done.

I'm trying to setup a render server on a Ubuntu 17.10 server, MediaWiki is 1.30 and Collection extension is the one in snapshot ba6fa49 for MediaWiki REL1_30. Render server is a separate server.

My LocalSettings is configured as:

//Extension Collection

require_once "$IP/extensions/Collection/Collection.php";

$wgCollectionPODPartners = false;

$wgCollectionFormats = array(

   'rl' => 'PDF', # enabled by default

   'odf' => 'ODT',

   'epub' => 'e-book (EPUB)',

);

$wgGroupPermissions['user']['collectionsaveascommunitypage'] = true;

$wgGroupPermissions['user']['collectionsaveasuserpage']      = true;

$wgCollectionMWServeCredentials = "Myuser:MyPassword";

$wgCollectionMWServeURL = "http://myRenderServer:8899";

I checked my render server against Wikipedia Article with

mw-zip -c :en -o test.zip Acdc Number

mw-render -c test.zip -o test.pdf -w rl

and also with MyWiki Article with

mw-zip --username="Myuser" --password="MyPassword" -c http://myIPAddress/w -o test.zip TestPage

mw-render -c test.zip -o test.pdf -w rl

in both cases the Article was rendered correctly, but when I try to render the same Article from inside MyWiki I got the error reported down here. I checked and re-checked, the base_url path is correct. I saw and old bug about this, but It was solved since REL_1.27. Any Idea ?

new-collection 1        'http://myIPAddress/w'        'rl'

2018-01-31T02:01:08 mwlib.serve.bad >> bad base_url: 'http://myIPAddress/w'

myIPAddress - - [2018-01-31 02:01:08] "POST /cache HTTP/1.0" 200 283 0.005379

Thanks in advance.

I am the admin on a low volume wiki that uses this extension. Our configuration uses the default value http://tools.pediapress.com/mw-serve/ for $wgCollectionMWServeURL.

Some of my users are periodically reporting that when they click on ''Download as PDF'', they sometimes get an error message: ''book rendering failed - there was an error while attempting to render your book''. 

Is there any log files/debug options that I can use and/or configure on my side to figure out the cause of the failed PDF rendering?

Hi, I've been trying to set up the Collection extension on my own rendering server, so I can generate pdf files from my wiki. So far no luck.

Here's where I am:

I followed this guide:

http://edutechwiki.unige.ch/en/Mediawiki_collection_extension_installation

And I can create pdf files from wikipedia using:

mw-zip -c :en -o test.zip Acdc Number

mw-render -c test.zip -o test.pdf -w pdf

mw-zip works just as one would expect.

---

mw-zip -c :en -o test.zip Acdc Number

I can read those pdf files, so I know my basic render farm setup is working.

The problem is that I cannot get it to work with anything other than wikipedia.

If I try the URL in the guide:

I as using Mediawiki 1.23 and I am not behind any proxy and also I disabled SELinux.

Variables that I am using in LocalSettings file are as follows:

$wgServer = "http://IP:portno";

$wgScriptPath = "/wiki";

require_once "$IP/extensions/Collection/Collection.php";

$wgCollectionMWServeURL = 'http://IP:8899'; (default port of mw-serve)

$wgCollectionMWServeCredentials = "username:password";

$wgEnableAPI = true;

I can't even begin to work on the actual extension interface until I have this working..... Any suggestions? Where do I go next?

Any help would be appreciated!

Thanks!

Guys! I would really appreciate any kind of help or just point me in the right direction, coz I am banging my head here.

Thanks!

Hello Solanki. Is your server running on Ubuntu? If so did you read Setup a render server on Ubuntu 12.04 LTS? If you follow the guide you should be able to get your server up and running. It currently explains how to setup on Ubuntu 12.04 LTS but I am testing it on 14.04 LTS and this seems to work just fine also. When I am done I will update Setup a render server on Ubuntu 12.04 LTS. Regards.

Hi Felipe. No, my server is running on RHEL 6.5. The strange thing am encountering is its different behavior to different sites, like I mentioned above, it works perfectly fine for Wikipedia, however gives a different error to http://edutechwiki.unige.ch/mediawiki/ and a different one for my site i.e. mw-zip -c http://IP:PortNo/wiki/api.php/ --username=uuu --password=ppp -o test2.zip Test.

Now, this is what's boggling my mind. I have almost gone through every document possible.

(Errors related to different sites are given above.)

Yay! I'm getting this exact error ("cannot guess api url...")

And my server was working before....

HI,

we have the similar kind of setup in our RHEL6 server and we render the PDF documents successfully. But, here the issue is the PDF doc could not contain all the embedded JPEG images in the wiki article page and it only intakes .PNG pictures in the PDF document.

Could some one please advise with solution for this issue? It would be really appreciated !

Thanks in Adv,

Sanjay

Hi, I have the same problem. Did you find any solution?

It's a problem with gevent. Coros was deprecated and is now removed.

Downgrade to a previous version with

pip install gevent==1.0

Thanks a lot, it seems to work now, at least for simple articles.

I had an older version of the render server running on Ubuntu 14.04 and it seemed to work better:

- The rendering page updated automatically. Now I have to reload the page manually.

- It seemed to work for more complex pages. Now I very often get the error "WARNING: Article could not be rendered - ouputting plain text.

Potential causes of the problem are: (a) a bug in the pdf-writer software (b) problematic Mediawiki markup (c) table

is too wide"

Okay, I hacked Image.py of Pillow to make tostring available again. Now more pages can be rendered properly.

I wish the render server components would be upgraded as they seem to be quite outdated.

I ran into the same problem. I found out that gevent.coros was renamed to gevent.lock. Therefore you could also update the code of mwlib by doing:

find . -type f -exec sed -i 's/coros/lock/g' {} \;

I also got the error KeyError: 'revisions', and solved it by replacing revs = e["revisions"] with revs = e.get("revisions","") in pp/local/lib/python2.7/site-packages/mwlib/net/sapi.py:311.

Running newest mwlib and collection...

Not a reel fix but see: https://www.mediawiki.org/wiki/Topic:Rokm611ol9px8vcg

Can't get the print/export menu in the sidebar to show up in custom namespaces. It shows everywhere else. Any ideas of how to fix this?

I believe you will have to add this namespace to the $wgCollectionArticleNamespaces configuration parameter.

Thanks. I had already done that but rechecked and had a typo. All good now.

I'm running the latest version of the extensions on MW1.25alpha and I'm seeing that when I click 'Download as PDF', the licensing information shows License: unknown. I have the following variables configured for the extension, as well as the default for the whole wiki:

$wgLicenseName = "Creative Commons Attribution-Share Alike 3.0 license"; $wgLicenseURL = "http://en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_Attribution-ShareAlike_3.0_Unported_License";

Shouldn't the licensing info appear on the PDFs as configured?

Thanks

I tried setting:

$wgLicenseName = null;
$wgLicenseURL = null;

As I have the following configured:

$wgRightsUrl = "http://creativecommons.org/licenses/by-sa/3.0/";
$wgRightsText = "Creative Commons Attribution-ShareAlike";

According to the ReadMe in the Collections source tree, the license should default to the Rights text in this case. It doesn't. Rendered PDFs and Books still have a License: unknown.

It's probably time to report an issue at phabricator.

You're right.

Thank you for doing this. This issue is actually a bit worrisome since licensing is an integral part of providing content. So the correct attribution is something that should not be missed.

Indeed, I've already argued that the extension should not output at all any content which can't be attributed.

I'm very curious how this is working on WP and not my wiki? Can anyone else reproduce this?

Same here, I'm on MW 1.27 and Collection 1.7

License for all the images is Unknown even though it is clearly mentioned as CC-BY-SA 4.0 and this is also same for images of commons used with InstantCommons

Hello guys, I would like to generate the collection_id from set of article and use this collection_id to create the pdf file from Wikipedia
